11/9/2022 0 Comments How to calculate percent error![]() ![]() Percentage Error = × 100 Components of the formulaĪctual value: The actual value indicates the numerical value of particular reading. In other words, percent error is relative error multiplied by 100. Since percent error is expressed in the form of percent, multiply the number thus received by 100. ![]() Subtract both these values and then divide them with the original value. One is the exact value, and the second one is the approximate value. To calculate percent error, you must have two available values. More minor percent errors mean that we are close to the original value, while more substantial percent errors mean a considerable discrepancy between the actual value and approximate value.įor example, a 2% error would mean that we are very close to the original value, while a 56% error would mean a massive difference between the actual and approximate value.Įrrors while measuring are pervasive because hands may shake during measurements, instruments may be faulty, material may not be precise, etc. Percent errors help us to determine how significant our errors are during any analysis. Errors may occur because of precision error in a machine, computing error, measurement error, or environmental conditions. ![]() You can express percent error as absolute error or relative error. This percent error is expressed as a percentage and hence multiplied by 100. Percent error in a collection of data is the difference between the exact and approximate values compared to the original value. ![]()
